Trying to change from units of atmosphere to units of bar? Use this simple and accurate atm to bar pressure converter for any calculation! More available.

To measure pressure, you might do so with units of **atmosphere** or **bar** that are commonly found to calculate air pressures. Pressure is measured by any unit of force divided by any unit of area, however it is simpler to use set units of pressure instead. The bar has recently been seen as a more universal and popular choice of unit, seeing that the atmosphere is beginning to be used less. View our other pressure converters and use our **atmoshpere to bar calculator**.

## How to use the Converter for Atmospheres to Bars?

Above, enter in the box the amount of atmospheres you need to change and click “convert” for an **atmosphere – bar conversion** that will present a new quantity of bars. To work the other way, convert bar to atmoshpere.

## Formula to Convert atm – bar

Provided below is the mathematical formula used by our accurate **converter of atm – bar** that you can use yourself if you wish to do the calculation by hand. For instance, 17 atm = 17.23 bar and 66 atm = 66.87 bar

**[number of] atmospheres x 1.01325 = [number of] bars**

## What are atmoshperes?

The unit of **atmoshpere** measures pressure through the force of an object exerted on a surface by the weight of air above it, or in other terms the Earth’s atmoshpere. Atmoshperic pressure is measured by a piece of equipment called a barometer, which is commonly used in meteorology. Above is our **atmosphere – bar converter**.

## What are bars?

Air pressure is measured in **bars**, a unit of gauge pressure. The bar can be divided into millibars and multiplied into kilobars depending on the scale of measurement that needs to be taken. Its use is found in the industries of meteorology, oceanography and geology. Try out our **atm to bar converter**.
